Thaum lub Plaub Hlis, 2019, Haiyuan tshuaj siv lub zog-txuag kev hloov pauv ntawm propargyl cawv muab faib hluav taws xob twj tso kua mis rectification nyob ib ncig ntawm lub tuam txhab kev xa tawm tag nrho nrog lub hom phiaj ntawm kev ntxiv dag zog rau kev tswj hwm cov tshuaj zoo thiab qhov pib ntawm kev txhim kho cov khoom zoo thiab txo kev noj.
Lub zog-txuag thev naus laus zis ntawm propargyl cawv muab faib cov cua kub twj tso kua mis distillation yog optimized los ntawm Tianjin University Raws li cov cuab yeej ua haujlwm uas twb muaj lawm thiab siv software txheej txheem simulation suav.Lub tshuab diaphragm distillation thiab cov tshuab cua kub twj tso kua mis distillation yog ua ke rau thawj zaug, thiab cov cuab yeej no tau siv rau cov txheej txheem ntawm cov tshuaj propargyl cawv thiab 1,4 butynediol thawj zaug.Lub zog hluav taws xob yog siv los hloov chav, kom lub zog noj yuav tsum tau muaj nyob rau hauv cov txheej txheem concentration ntawm propargyl cawv thiab butynediol tuaj yeem txo los ntawm 25% piv nrog cov txheej txheem, thiab cov nqi txhua xyoo tuaj yeem txuag tau los ntawm 20million yuan.
Lub tshuab diaphragm distillation yog ntxiv ib lub diaphragm ntsug nyob rau hauv nruab nrab ntawm cov pa distillation kem, thiab faib nruab nrab ntawm cov pa distillation kem rau hauv ob qhov chaw: sab pub thiab sab rov qab.Hauv kev siv tswv yim, rau kev sib cais ntawm peb yam, cov khoom ntshiab tuaj yeem tau txais nyob rau sab saum toj, nruab nrab thiab hauv qab ntawm tus pej thuam, raws li kom paub txog kev sib cais ntawm peb yam hauv ib lub pej thuam.Lub zog txuag txoj cai ntawm diaphragm distillation thev naus laus zis yog ua ke ua ntej kev sib cais ntawm cov khoom siv nrog distillation, txo cov backmixing ntawm cov ntaub ntawv thiab qhov nyuaj ntawm kev sib cais, thiaj li yuav txo tau qhov pib peev thiab txo cov nqi khiav lag luam.Lub diaphragm distillation tshuab yog tshwj xeeb tshaj yog haum rau lub system yuav tsum tau sib cais nyob rau hauv uas lub nruab nrab boiling point cov ntsiab lus rau feem ntau thiab lub teeb Cheebtsam thiab hnyav Cheebtsam account rau ib tug me me, thaum txuag li ntawm 30% ntawm cov thawj peev.Cov ntaub ntawv raw rau cov concentration ntawm propargyl cawv yog propargyl cawv 3.2%, dej 90.8%, thiab butynediol 6%.Dej, raws li cov khoom nruab nrab, suav rau feem ntau, uas ua tau raws li cov kev pabcuam ntawm diaphragm distillation technology.
Nyob rau hauv 3-5 xyoos tom ntej no, Henan Haiyuan Fine Chemical Co., Ltd. tau cog lus los ua tus qauv ntawm Tuam Tshoj txoj kev lag luam tshuaj zoo, thiab siv zog tsav kev lag luam kom coj ntsuab, txuag hluav taws xob, zoo thiab siab- tech txoj kev los ntawm nws tus kheej txoj kev loj hlob.
